Grieg's Third Violin Sonata is one of his major creations and stands alongside the sonatas of Johannes Brahms and César Franck at the pinnacle of late nineteenth century chamber music. One small measure of the work's renown is its occurrence in Thomas Mann's novel Doktor Faustus. The sonata has been growing more popular ever since its first publication, and it is now high time for it to appear in an urtext edition from Henle. A preface and detailed editorial notes provide interesting background material on the work's source tradition.
